Apple has retired the Mac's Launchpad, a feature that displayed all your apps and let you quickly pick the one you want to open. You can recreate the app launcher using these alternatives. The latest version of macOS, named Tahoe, added all kinds of new features to the Mac desktop. It also removed one: Launchpad. The feature, which gave Mac users an iPhone-like grid of applications complete with support for folders, is missing from macOS 26.

Our columnist on digital culture suggests technology--or anti-technology technology--to give this holiday season. We are entering a Surrealist phase of personal technology. Any device you might imagine can be found online courtesy of an obscure Chinese factory, ready to be shipped out for a loved one's holiday enjoyment: pocket-size artificial-intelligence gizmos ( Rabbit r1, $199), in-home hologram machines (Code 27 Character Livehouse, $558), human-size robot servants ( 1X NEO, $20,000). The components of tech have become better and cheaper, from microchips to speakers and screens (have you seen how cheap a good TV is these days?), enabling out-there innovation. On the consumer side, we are bored of rote device designs; we've seen a dozen models of iPhone and crave something refreshingly different.

Cross-frequency transfer learning (CFTL) has emerged as a popular framework for curating large-scale time series datasets to pre-train foundation forecasting models (FFMs). Although CFTL has shown promise, current benchmarking practices fall short of accurately assessing its performance. This shortcoming stems from many factors: an over-reliance on small-scale evaluation datasets; inadequate treatment of sample size when computing summary statistics; reporting of suboptimal statistical models; and failing to account for non-negligible risks of overlap between pre-training and test datasets. To address these limitations, we introduce a unified reimplementation of widely-adopted neural forecasting networks, adapting them for the CFTL setup; we pre-train only on proprietary and synthetic data, being careful to prevent test leakage; and we evaluate on 15 large, diverse public forecast competition datasets. Our empirical analysis reveals that statistical models' accuracy is frequently underreported. Notably, we confirm that statistical models and their ensembles consistently outperform existing FFMs by more than 8.2% in sCRPS, and by more than 20% MASE, across datasets. However, we also find that synthetic dataset pre-training does improve the accuracy of a FFM by 7% percent.

Science Biology Humans sync their blinks and brain waves to a song's beat Our bodies react to music whether we want it to our not. Breakthroughs, discoveries, and DIY tips sent every weekday. A good song can easily get a listener nodding their head or tapping their foot along to the beat. While you may not initially realize you're doing it, those physical responses to music are still conscious decisions that you can stop whenever you want. According to neuroscientists, however, music also has the ability to influence even some of our involuntary movements.

From runaway robots to "sonic bombs," we reviewed offbeat alarm clocks designed to awaken even the heaviest sleepers. Not every alarm clock is created equal. Heavy sleepers know how easy it is to snooze through the overly genteel alarms on your phone. For people who can't get out of bed without a bigger jolt, extreme alarms have popped up in recent years--from relatively simple puzzle-alarm phone apps to alarms on wheels to alarms that shake the bed. Not only are these an innovative way to get chronic snoozers out of bed, but they can be great for those who are hard of hearing, utilizing different frequencies and pitches as well as movement through vibration.
